Multiple wavemode scanning for near and far-side defect characterisation [PDF]
, 2020 The combination of ultrasonic inspections using different wavemodes can give more information than is available with single mode inspection. In this work, the response of shear and Rayleigh waves to surface-breaking defects propagating on the near-side ...

Measurement of interface pressure in interference fits [PDF]
, 2005 When components such as bearings or gears are pressed onto a shaft, the resulting interference induces a pressure at the interface. The size of this pressure is important as many components fail because fatigue initiates from press-fit stress ...

Interfacial fracture behavior of a stainless/carbon steel bimetal plate in a uniaxial tension test
Results in Physics, 2019 The interfacial fracture behavior of a stainless/carbon steel bimetal plate in a uniaxial tensile test was investigated in this paper. The ultrasonic C-scan results showed that the internal fracture had already appeared in the necking area before the ...

A noncontact ultrasonic platform for structural inspection [PDF]
, 2011 Miniature robotic vehicles are receiving increasing attention for use in nondestructive testing (NDE) due to their attractiveness in terms of cost, safety, and their accessibility to areas where manual inspection is not practical. Conventional ultrasonic
